Sky Bet Championship clubs Fulham, Nottingham Forest and Bolton have all been placed under a transfer embargo for the rest of the season after breaking Financial Fair Play rules during the 2014-15 campaign, the Football League has announced.

Fulham and Nottingham Forest were sanctioned after exceeding an adjusted loss of £6million - the maximum rules allow - while Bolton were punished after being unable to submit their FFP return owing to their current off-field situation which has seen them served with a winding-up petition by HMRC over an unpaid tax bill.

The punishment means that all three clubs will be unable to sign players in next month's transfer window.

Last season's Championship winners Bournemouth also posted losses of more than £6million and will face a fine, the amount of which is yet to be revealed.

Millwall, who were relegated to League One last term, also went over the maximum deviation of losses, but will not be punished.
